Neither the tooltip for Eternal Flame on the action bar nor the tooltip for EF in the spellbook says anything about "+49% of Spell power". It does say "... which heals them for 16,895 to 17,494 and an additional 2,659 every 2.31 sec for 30.07 sec." I've long been aware that those numbers change without knowing what changes them. The description on Wowhead (
http://www.wowhead.com/spell=114163) does say "... which heals them for 5240 to 5837 (+ 49% of Spell power) and an additional 711 (+ 8.19% of Spell power) every 3 sec for 30 sec." Granted, I know that Spell Power is a stat on the paladin paper doll, and that is all I know.
Pretty much every spell in WoW works this way. It does some base damage plus some extra damage based on your spell power and/or attack power. For Eternal Flame, this is
total_damage = rand(5240,5837)+0.49*spell_power
where I'm using rand(x,y) to indicate a random number between x and y. The value 0.49 is Eternal Flame's
spell power coefficient. Wowhead doesn't know your spell power, obviously, so it reports the base damage and the spell power coefficient.

From the tooltip for Vengence: "Each time you take damage, you gain 1.5% of the unmitigated damage taken as attack power for 20 sec."
You gain attack power from vengeance which is converted to spell power via Guarded by the Light, which in turn impacts Eternal Flame.
I've probably read the entries for Guarded by the Light and Vengeance a dozen times without making the connection to Eternal Flame, because of the way EF is described in the game UI tooltips, and I wasn't thinking of them while reading the description on Wowhead. So this chain of arithmetic endures for 20 seconds "each time you take damage". Does "damage" include damage from spells, or is it only physical damage? ....
Vengeance is based on the raw damage the boss deals before any mitigation effects for various reasons, but mostly so that it doesn't penalize you for increasing your survivability. So you get vengeance every time you take direct damage from an auto-attack or spell, AND every time you avoid a melee attack. When you avoid, it uses the boss's raw damage it would have done had the attack not been avoided. Spell damage also grants 2.5x as much vengeance as melee damage (to make up for the fact that you have much less mitigation for spells thanks to armor).
The one caveat is that they can "turn off" vengeance from any given spell, so most persistent area-of-effect damage sources that you're not supposed to stand in do not grant vengeance (to avoid the incentive to stand in that damage source to game the system).
As a player, though, you don't really need to worry about how the calculation works. You just need to know that you'll get more attack power (and thanks to Guarded by the Light, spell power) from harder-hitting bosses, which makes your Eternal Flames (and most everything else) stronger.

The default UI is not all that great for this sort of communication. There are a variety of AddOns that give you a better display of such things. I have a set of
WeakAuras that gives text displays for Vengeance, amongst other things.

Again, it's just like spell power. Most spells do (base_damage + AP_coefficient*attack_power + SP_coefficient*spell_power), where at least one of (SP_coefficient, AP_coefficient) is nonzero. There are a few spells where both is nonzero (Judgment, for example, scales with both).
Adeya wrote:From Mastery, Divine Bulwark: "adds 8% to your Bastion of Glory"
The title is "Mastery: Divine Bulwark" and other than the word "mastery" in the title there is no mention of any explicit connection between how much Mastery the paladin has and any benefits of the passive spell "Divine Bulwark", which appear to be constant. Then again, I can't say that I've ever recorded the numbers and checked subsequently to see whether they change when Mastery changes.
The 8% value is given by Wowhead (
http://www.wowhead.com/spell=76671). Currently the spellbook entry for my paladin says "... adds 20% to your Bastion of Glory, ...". Heh. 20% of what? Not the amount of coins in his backpack, I'll wager. :-) Maybe each stack bonus is 10.2% instead of 10% since .2% is 20% of 10%. There are other possibilities and that doesn't seem likely to be the one.
Every class's mastery has a name, ours is "Divine Bulwark." All classes start with a base amount of mastery, which is usually 8% (there are exceptions, but this is not a detail you need to worry about for now). As you stack mastery rating, you'll see your character sheet mastery percent increase, and the tooltip will say "X rating gives Y%;" it's easy to verify that 8%+Y% is the total displayed on your character sheet, which is also what shows up in the Divine Bulwark tooltip.
Bastion of Glory's mastery bonus is additive. So if you have 20% mastery, Bastion of Glory will increase the strength of Word of Glory (and Eternal Flame) by 30%. Again, this is easy to verify by reading the tooltip in-game.

Last caveat: Tooltips can lie! Word of Glory's tooltip was wrong for the first half of MoP, in fact. But there are people out there who verify such things every expansion, so at least as of right now these tooltips are accurate.
