You can learn to do basic proofs the way old school Tsarist and Soviet Russia students did, by studying geometry from Kiselev. It should be pretty straightforward for any adult, and a nice stepping stone to build your knowledge on. A more advanced approach would be to go through a logic book like Velleman that teaches proofs as structured programming.
