Is there already an WoTC feat for extra smites?
Just want to make sure we don't rewrite it.
There is, but there's also OGL versions, too. It's a pretty common feat. I think the wotc version is from 3.0, and it gives +1 (which is tiny).
It's not in the SRD.

RA: Smites aren't vastly superior at higher levels. In fact, they're worse. At low levels, smtie and rage are about equal in damage ability (the rage is all around better, since it offers HP and Will save bonuses, but that's not the point here).
I'll give the math. Let's assume we have a barbarian and a paladin, with 10s in all stats (silly, I know, but it makes the math easier). Both are humans. Let's also assume that they only fight evil opponents (or it tips things even more in favour of the barbarian) One has taken extra rage, the other extra smite.
At 5th level ('high level' for us), the barbarian will have 4 rages per day, while the paladin will have 4 smites.
The Barbarian can rage for a total of 20 rounds per day, and has a +2 bonus on attack and damage while raging. Yeah, there are peripheral effects, too, but let's just look at combat.
Assuming the barbarian hits about half the time, that's 20 points of bonus damage.
The Paladin will get a small bonus to her attack roll (if she had a charisma modifier), and deals 5 extra points of damage per attack. If she hits half the time, that's 10 points of bonus damage.
At 10th level:
The barbarian's gets 5 rages per day, at the same bonuses. That's 25 rounds. Again, assuming half the attacks hit, it's still around 25 points of damage.
Our paladin has 5 smites. Each smite now does 10 points of damage. Assuming half hit, that's... 25 points of damage.
20th level changes things, though.
The barbarian will have 8 rages, each at +3 to attack and damage. And they last longer (6 rounds a rage, and he's no longer tired!). So, 48 rounds per day of rage. If half his attacks hit (and the bonus has gone up, meaning the barbarian is more accurate than the paladin), he's inflicting 72 points of bonus damage.
Our paladin has 7 smites, each at +20 on damage. No big changes. If half hit... he's dealing 70 points of damage.
But there's a catch - at 20th level, the raging barbarian is making 4 attacks per round, while the smiting paladin is making one. Which ups the damage potential of the barbarian. About the only advantage a smite has over a rage is that there's no exhaustion at the end, and that you can make multiple ones per day - So our paladin can smite 7 rounds in a row... while our barbarian can stay in a single rage for 6.
There's a definite closeness in the numbers, but I think there's still a slight edge on the barbarian.
