One tip is not to stand behind the minions in this match up, that way he needs to choose between using his E on the minions or on you, if he uses it on the minions you don't take damage and if he uses it on you then his shield strength is reduced since he only hit one target, so it's easier to trade back. His shield strength isn't affected by spellvamp, it actually just depends entirely on how much damage he dealt. He also needs to get into melee range early to last hit, so you can harass him with autos, and since he tends to push the wave you could ask for a gank. Getting an early Abyssal(before hextech) can help vs him since he deals magic damage and Vlad gets a lot out of the item. I take magic pen reds, health yellows, 6 flat CDR and 3 scaling CDR blues and spellvamp quints on Vlad with 9/21/0 masteries when I play him top, but another Vlad player I know takes MR per level blues, armor yellows, M.pen reds with spellvamp quints and runs 21/9/0 masteries, so you might want to also try some alternate setups even changing it up depending on the match up.
