First, I picked up some 1.5" x 1.25" protoboard from a local shop. I got ones where none of the pads are connected by default:

Now we can add the copper tape. You can use whatever pattern works for you, but I like the one I've come up with. It uses a common ground wire for all the buttons reducing my wire count. You're going to want to make sure there is a small gap between your pieces of tape so as not to bridge any connections.
