Race: Breton
The main reason I picked Breton is for the Dragonskin ability and magic resistance. I feel both of these abilities will aid my vampire the most in the long run, if the vampire lord form is anything like werewolf form then I will be able to activate http://elderscrolls.wikia.com/wiki/Dragonskin_%28Skyrim%29 and http://elderscrolls.wikia.com/wiki/Dragonhide before I transform.
Attributes
Magicka 25%
Health 60%
Stamina 15%
So when the character is maxed out it will look something like this:
Magicka 300 / 350*
Health 650 / 700*
Stamina 150 / 200*
*Power of the Grave perk + 50 to Magicka, Health, Stamina while in Vampire Lord form.
You might ask why so many points in Health? I choose this so my vampire lord is extremely resilient in vampire lord form and doesn't get taken out in 1 or 2 hits in master difficulty. Additionally a large health pool with equilibrium also makes for a large magicka reserve if needed.

As far as armor goes I would just go with the vampire armor you like the best. With Dragonhide and being a necromage vampire + stability perk will last over 3 minutes.
When not in Vampire Lord form the character will use Illusion to start infighting with spells like frenzy or mayhem. Dual casting Frenzy can be very powerful and has a good range, once the enemy is devastated from fighting each other you can send in your thralls (which should be master vampires) to clean up.
What do you guys think?
