The best advice I have is to get involved with your dreams. Remember them. Think about them. Try different techniques and just have fun with it all. You obviously have some experience with lucid dreams so I'm sure you'll get back into the swing of it fairly easily. WBTB is the easiest technique for myself personally to get back into it lucid dreaming when I've been in a rut. If you have any specific questions there's a lot of people here who have a lot of personal experience and can help you. Check out the tutorials as well.
