2x1(X and Z) tunnel straight down placing ladders to get out. When Y=13, dig a 2x1 (Y and Z or X) in any direction. Do not stop until more supplies are needed or I feel uncomfortable carrying my loot.
You could have the tunnel go 100 or so blocks, and then turn and end up making a giant square, but that requires more coordination. If I ever branch off of that original tunnel, I do with three blocks between each branch. All of these tunnels at Y=13.
Diamonds generate below Y=16. Lava generates below Y=64, but it is rather rare above Y=13 or so. Y=13 is the surface of most of the giant pools of lava deep in the ground, so you should be safe if you pay attention.
