There was one three month period of my life where I had frequent lucid dreams and was able to astral project, but when my sleep schedule changed and I got stressed out, it went away. It took me a years, and all of a sudden the timing was just right and it would happen.
I used to do the astral projection meditations by Susannah Is This a Dream a lot:

They're all really beautiful meditations, but the astral projection ones helped me feel OBE sensations. Some of them are also suppose to guide you into a lucid dream, but like the astral projection ones, they never really worked, but they helped me get into a hypnogogic state which is good practice.
I also recommend the book Are You Dreaming? by Daniel Love. He takes a really scientific approach on it, but even though he doesn't believe this could be a spiritual tool, I think he breaks down some methods really well. He also has a section where he talks about the sleep cycle which plays a really important role in when you're able to lucid dream. It really helps me to look at it this way where you have step by step instructions and you can try different things and tweak them yourself so you don't have to just fall asleep and hope for the best. He also has section on how to stay asleep when you're lucid and what you can do when you're lucid.
One of the methods I've learned in this book which was very helpful to getting me into lucid dreaming again was his journaling method. He says you not only need to write down your dreams, but you need to highlight and analyze dream signs. For example, one theme that always shows up in my dreams is calling 911 and no one answers. When I'm dreaming, and this happens, I always realize it's a dream. This is also when you do your reality checks. For example, if a common theme in my dreams is being late, I always do a reality check when I'm running late for something.
I hope this helps! Once again, I highly recommend the book. It really got the process going for me
