Short answer: yes.

Long answer: Whatever you wear that boosts either your magicka pool or magicka regen (along with Health boost / regen) will remain. The form adds its bonus on top of whatever you have. Sadly, nothing you wear that affects magic schools has no effect since your Vamp Lord uses
Blood and
Night magic.
Spoiler Later you will get 4 Vampire Lord specific items (2 rings, 2 amulets) that will help boost or enhance your abilities in Vamp Lord Form. They come randomly from the radiant quests.
