If the bathroom wall switch is working you might have to start looking at the wiring for the lights themselves.

I had to pull down all of my lights for the same problem. I believe that one of them had a wire shorting against the aluminum shell and it kept all of the lights from working. For me it was the one in the furthest back, over the bed, which also has a ground strap for that circuit.

I'm still not sure why it didn't blow a fuse but kept the lights from working. You might try unscrewing the light fixtures from the ceiling and taking a look at the wiring.
