If you put a male in with the female you've done it. When she gets really fat, give her a box of moist sphagnum moss and wait. Two eggs will appear in the moss. Ta-da! It could not be easier to do. If you need more info than that I would recommend search engines like Google, or caresheets from this forum, or buy a book on Leopard geckos.....
Breeding leopard geckos is really the easiest of all reptiles in my opinion. Also kinda hard to mess up if you are keeping the adults correctly in the first place.
