Wake-back-to-bed technique, google it. Standard methods of dream recall, dream journal, reality checks during day don't do anything for me. But if I wake up at 3 AM, either with an alarm clock or just psyching myself to do it, stay up for an hour or so and read something to wake my brain up a bit and then go back to bed, there's a good chance I'll have a lucid dream after falling asleep.
