Electrical Wiring in the Home/double pole switch wiring

It sounds like the nm cable at your current switch is a hot, a switched hot and ground.  More than likely the wiring comes from our electrical pnl to the fan/light then drops to the switch.  In order to make 2 separate switches work you will need an additional NM cable from the fan / light to the switch location.  There are double switches available that will not require you to cut in a larger box.  With the switch in the off position one of the wires on the switch will remain hot 120v ( most likely the white reidentified black) while the other will have no potential 0v. The hot wire would be tied to the line side of the switches (both) then you would tie the black to one load side, a second  would be needed to tie to the second switch load side.  These two wires would feed the switched hot to both the lights, and the fan respectively.  The neutral should be tied to both the lights and the fan at its current location.  Keep in mind that the light and fan are both currently tied to a neutral and a switched hot.  The the switched hots will need to be separated.
