You need one LFO, one inverter, two VCAs, and your audio signal. Audio  
signal goes to audio input on both VCAs. LFO output goes to VCA #1 CV  
input. LFO output also goes through inverter, the inverter output goes  
to VCA #2 CV input. You'll have to add a +5V offset to each VCA if the  
LFOs are +/-5V (most likely they are). I have a couple of panning  
audio examples at the bottom of this page:

The VCAs I used for these demos have reversing attenuators built in.
