I always enjoy progressing the chracter from the slums to the riches. Start with Arena, then Fighters Guild, do KOTN, and if it suits, the main quest.
The Ritual birthsign is good for the paladin.
Role play him/her so that your goal is to rid Cyrodiil of all signs of tanted evil- undead, necromancers etc. Dungeon dive in only those places that have those guys out the front.
Use heaps of healing, shield spells and make up custom spells like-
Undead Lantern
Turn Undead + Fire Damage.
And make the character a follower of Arkay.
