I lay on my back. I put some small amount of thought into things like "chi" by make sure that my palms are open and my legs are uncrossed.
Concentrate on relaxing your body, starting with the toes and working up. Don't move on until you find full relaxation first (at first, to fully relax will actually cause the muscles to either hurt or tickle. With practice you will get better at it, and the muscles will learn to respond to the release of stress by not aching).
For me, i visualize. I visualize the stress as being small creatures, and i push them up and out the top of my head. As i go through each body part, the "gremlins" scurry out and seek safe harbor by leaving my body and dispersing.
Once i am relaxed, i can begin guiding thought. This is where i "pray" for people. I don't believe that our Creator hears our prayers. I believe the "souls" on the "other side" do, and that is where the help comes from, if it doesn't cause deviation from our lifes planned path. Consequently, i don't believe that you can ask for things, but rather can ask for guidance, courage, strength, etc. (this whole concept has a basis in science, as there are studies that show human awareness and intent can effect the outcome on reality).
Once i have put others before myself by "praying" for them, i begin sorting through my own issues. I visualize to do this, too. Using visual "files" and "folders" to track what needs to be "done" and what is already completed (by "done", i mean putting my attention and awareness into a solution).
Once i have done this, i try to allow my mind to go completely blank. At this point, i normally also go to sleep.
My main issue is that i cannot achieve a "blank state" without falling asleep. Damned narcolepsy!
