I've been running this paladin build, and with the 1.06 patch changes, it's much more effective, so I thought I would post it here.
I used Pallegina customized with IE Mod to change her attributes. I don't feel like race makes a huge difference in this game, but Hearth Orlan is the obvious best choice for maximum DPS. Moon Godlike if you want a bit of protection in case she gets hit. Since I used Pallegina, I couldn't choose my order, but Kind Wayfarers would be a good way to go for some healing.
She's not flashy, but she provides consistent DPS from a safe spot just through auto attacking while providing support through auras.
With the aura size changes, Zealous Focus is big enough to provide your entire party bonuses in most situations, though that depends on how you position your ranged attackers. This build is good to combo with any other class looking to stack crits, like Rogue or Ranger.

Gear
I used the Tall Grass Pike (Increased Reach; +10% Hits converted to Crits; Crits can inflict Prone) to take advantage of Increased Reach and the crits resulting from accuracy stacking. Basically just sit back behind your tanks and poke stuff, looking for crits, knocking enemies Prone, picking off low endurance enemies (Bloody Slaughter and Strange Mercy are great for this) and providing support through your auras and exhortations.
For a secondary weapon set, I use Azureith's Stiletto (DR Reduction; Spell Strike: Jolting Touch) and Sura's Supper Plate (Small shield, Retaliate) for clearing large weak mobs. Turn on Vulnerable Attack and/or use Sworn Enemy for punching through high DR.
I usually had her in a piece of light armor because I had no problem keeping her out of trouble. Go plate if you expect to be taking more hits.
The other piece of gear that's been helpful are the Boots of Zealous Command (x1.2 aura size).
Note: I'm writing this up from memory, so I apologize if I have the wrong number of talents/abilities. Think I got it right, though.
