You give them access to a domain from what I can see, but I can't find more than a brief mention of it .in the Spellcasting section:
The paladin has access to domain spells or granted powers, as a cleric does.
Might wanna expand on this just a little, it's easy to miss just now.
Otherwise looks like a nice remodelling in honesty. I've never been too fond of LG paladins as a rule, I personally prefer the paladin of freedom just for the fluff so this is a welcome tweak. 5th level spells make a big difference to this too, nice compilation of spells.
