When I mid with Karthus I usually don't have a problem early game. Here's why:

Don't miss with your Q. Predict where you think they'll be. It's excellent harassment. This will take practice.

Get your W at level 2. Why? Because your W makes it really easy for them to be harassed with your Q. And your early game is helped a lot if you're able to zone them, even a little.

Also get blue. Karthus needs blue. Lots of Q needs lots of mana.
