Narrative:
Everything was normal until rotation when the flight director disappeared and the auto pilot disconnect horn and warning light activated. While cleaning up the aircraft the master caution; mach trim and yaw damper lights illuminated. We were now VMC above a cloud layer and started to complete the mach trim failure checklist. A flight attendant then called to report smoke and fumes in the cabin.we donned our oxygen masks and completed the memory items for smoke in the cabin and cockpit. I was the pilot flying and flew the aircraft for the return approach and landing. The captain declared an emergency; communicated with the flight attendants about the condition of the cabin and passengers; completed the smoke removal checklist; and set up the aircraft for the return to our departure airport. The autopilot and flight director were not available. Upon landing; the fire department escorted us back to the gate. The passengers were deplaned and the aircraft was turned over to maintenance. A preliminary inspection turned up a damaged inverter in the east&east compartment.
