Set up a game of Jenga, but have pieces of paper blu-tacked to each Jenga piece, with stuff written on it, such as names of God, or promises of God. Get the youth sitting in a circle, and play Jenga. Each time they take a piece, they have to read what is on it, and say a short thank-you prayer for what they have read. If the tower falls over, just build it up again. Afterwards we wrote some of the names of God that were on the blocks onto A4 sheets and stuck them around the room. The youth then went around the room and spent a few moments at each one, reflecting and saying thank you to God.
