Start a dream journal, or if you have one already, make sure you're posting/writing in it EVERY day. At least that'll get your recall up if that's the problem. Then look to make sure you're getting the right amount of sleep.

A trick I like to try is sleeping in different random places. I think it makes you hyper-aware or something, which helps to induce lucid dreaming. I discovered this when I would have way more LDs when I was vacationing.

Good luck
