Seriously, get a midi keyboard, and just jam along. Doesn't matter how terrible it sounds, you can quantise and normalize the volume later.
Also, draw inspiration (read: steal) from sweet-ass drummers.
For instance, I use a lot of adapted patterns in the styles of Gavin Harrison and Mike Portnoy in my rock drums as they are my favourite drummers. Just do some speculative viewing of the styles of music you want, find something that makes your jaw drop. Then learn why it does!
