There is only one lead from the yoke on the vertical side. What would I do with the other lead on the variac?

The other side of the vertical is connected to ground according to the schematic (most likely chassis ground somewhere.)
you _SHOULD_ be able to connect the neutral side of the variac output (Be careful that you do really have neutral!) to the chassis, and then the HOT side to your coil wire.
HOWEVER, before you do that, double-check that your chassis is actually grounded or connected to line neutral. If your set has the possibility of a "Hot" or floating chassis voltage (i.e you do NOT read close to zero volts when measuring voltage from chassis to neutral in the wall plug), DO NOT DO THIS - it could trip your breaker!
Since you know the transformer is good though, if driving it with the variac produces no deflection, you can be almost certain the coils are the problem... and the test you're unsure about will produce little extra information.
