Narrative:

Departing ZZZ at approximately 300 ft a burning odor was detected in the cockpit and the cabin. The flight attendants reported a burning smell along with haze and the right aft lav smoke detector sounding. We entered a downwind and an uneventful landing was accomplished back into ZZZ. During our return all appropriate checklists including our company's non normal procedures were accomplished.callback conversation with reporter revealed the following information: the reporter stated that the return to land was very routine and non hastened. The crew believed that oil had infiltrated the air conditioning packs; causing the smoke. The crew has not heard back from maintenance on the cause of the smoke.
