Welcome!

For beginners the best technique seems to be DILD/MILD, but you can also try WILD if you feel like. Here you have a link to a great post explaining lots of things about the technique and all day awareness.

Also if your dream recall is poor it would be a good idea to keep a dream journal, eventually your recall will be better and so will be your awareness and the vividness of your dreams, which will make it easier to get lucid.
For WBTB try to control your feelings, since if you're too excited it will be hard to fall asleep again.

Good luck!
