For me, the vast majority of my actual prayer is the Serenity Prayer. When I am feeling disconnected, I usually have a nice, long session of meditation, but most of the time I just talk conversationally to God. Generally I ask for signs and he usually provides them in one form or another, as long as I have not closed my mind to the possibilities. When you close yourself off to possibility, it is easy to find false "signs" that support your decision, but the only way to find the true signs is to keep an open mind and watch closely.
