PA-23 pilot reported loss of directional control on landing after encountering jet blast from a departing B767.

Narrative

During our approach to LAL ATC instructed us to start turning from right downwind to base and then final; clearing us to land on Runway 10. ATC cleared the B767 to take off and we were less than half a mile from touchdown. We observed the takeoff in order to avoid its wake turbulence. When we were about 5 or [so] ft. less to land; the left wing raised all of a sudden because of the wake turbulence and [the aircraft] touched down and got pushed to the right. The airplane steered to the right side of the runway and we ended up running over the grass on the runway side. We took action and throttled up the right engine to steer to the left and reached the runway again. We managed to taxi off Runway 10 and exit at [Taxiway] A3. Airport personnel approached us and checked the airplane and other ground personnel checked the runway and lights and informed and confirmed that we had not hit or damaged the runway lights. We are convinced that there was not enough spacing between the departing heavy jet and us landing after ATC cleared us to land. Also; there was another airplane coming behind us on final. For that reason; ATC called our base turn to accommodate for the other landing airplane. The outcome was no damage to the airport property; airplane; and passengers but this was a learning experience for all of us. Next time we will elect to reply to ATC that we are unable to continue with his instructions in order to avoid these kinds of situations. We strongly believe that ATC should give us priority to land and just wait 2 - 4 minutes during our landing and then release the heavy jet. It is just a matter of judging. Once we taxied to our destination in the airport the airport personnel approached us again and took pictures of the airplane landing and stated that this incident will not be reported to the FAA because there was no damage at all.
