Champion of Irori

Any advice on how to build a Champion of Irori? Starting at 5th level, planning on taking the PRC level at 6th. What would be the best setup?

Specific (relevant) houserules:
Stats are 4d6 drop lowest
Auto Bonus Progression at level +2, free masterwork gear.
Weapon Finesse, Power Attack, and Combat Reflexes are free feats if you meet the prereqs
Regular Monk is d10, full BAB, and proficient in all Monk weapons, UMonk has 3 strong saves
Paladin has 4+INT skill ranks.
Traded-out archetype abilities from 15th to 20th can overlap, game won't go that far.

Do you just want to be a paladin-like monk of Irori? If so, you might be better off being an Iroran Paladin 1/Sohei Monk 1/Iroran Paladin 18, since your houserules buffed regular paladins and monks but not the Champion of Irori prestige class. Being able to use flurry of blows with light armor with the Brawling enhancement is really nice, and regular monks can't do that.

Here's a guide to the Iroran Paladin.

If you actually want to have the Champion of Irori prestige class, I can't help, sorry.

Personally, I'm a big fan of one level of Oracle of Lore for a Champion of Irori. It's such a MAD build that the ability to dump Dex and focus almost exclusively on Str, Wis and Cha with a little dabbling in Con is super useful.

I'd strongly suggest either that or a Dex build.

What I'm really looking for is the ki pool conversion ability at 2nd level. Everything else is basically gravy, although being able to advance AC, Flurry, unarmed damage, Lay on Hands, Smite and Ki in a single class seems worthwhile enough to stick around.
