Which Length Lag Screw to use to join two pieces.

Hello,

I figure a picture will explain what I am trying to do better:

What length coach screw (lag screw) would be best? I am not too sure how far into the plywood I should be going. Or which diameter to get. I want to hold the plywood section tight to the section underneath. I want it to be as secure as possible, but I don't want any visible screws from the top.

Would like some advice also on pilot holes.
