Narrative:

Cruising at altitude in clear VFR controled airspace, told by controller to turn immediately to 270 degrees and climb and maintain 8500 ft (left turn). We did so. Controller then asked what was our previous instructions as far as track and told us we were off course by 4 NM. We gathered we were in conflict with terrain. Captain stated we were to left of mountain we could see, off to our right, less than 1500 ft below. When I reviewed FMS for course guidance, noted captain had programmed FMS for approach to vny, with final approach fix on wrong side of course, we were tracking to final approach fix not to 'vny airport direct,' as instructed. So we and our aircraft were flying too close to mountainous terrain and must have set off his GPWS early warning system. In closing, I also neglected to doublechk FMS when I did my approach brief to verify that captain had loaded FMS correctly while reviewing approach plate. In closing, this was first flight of day, with new captain after 7 days off.
