I have a Wall unit which used to have 4 12V halogens wired in. There
are 2 switches which used to work 2 lights each. I have doesnsized the
Wall Unit, so that there are now only 2 12V halogens. I have a bunch or
wires and a transformer from the old set-up, but am unable to get the
one switch to work to work the lights. What is the proper way to wire
this set up from outlet, to swithces, to lamps. I am not an electrician
obviously. But this should not be too hard.

If I bypass the switch, I can get the lamps to run, on constant on, but
would like to use the switch. When I try to wire the switch into the
flow, the lights go on when I plug them in, but when I try to turn them
off with the swith, it throws the circuit breaker. I am plugging the
whole thing into a normal wall socket.

Wire the two lamps in parallel and connect the switch in series with either
of the transformer secondary leads.

The switch interrupts one of the two wires going from the plug to the
transformer. If the plug is polarized, the switch interrupts the wire
connected to the smaller prong on the plug

So if I hear you right:
1) I connect one of the wires from the outlet plug to one of the wires
leading to the switch, and the other wire from outlet the plug to one
of the wires leading to the transformer.
2) Then I connect the other wire leading from the plug to the other
wire leading from the transformer.

Correct?

One of the wires from the plug goes directly to the transformer
The other wire from the plug goes to the switch, then from the switch to the
transformer
