I don't know what your present situation is but if you have one always hot wire for two switches, make up two short jumpers (some say pigtails) long enough to reach from the hot to the switch. Splice the hot and two jumpers with a wire nut and hook the other ends of the hots one to each switch.
The other screw on each switch will connect to the wire that goes to the fan and from the other switch to the light.
Turn off power first and use the same size wire for the jumpers as the existing wire.
