After rotation cabin and cockpit filled with smoke, #1 engine lost some thrust. Oil quantity #1 engine went to 1 qt. Retard throttle, smoke cleared some, declared an emergency and returned to lga. Shut down #1 engine after turning off the runway. Callback conversation with reporter revealed the following: a main bearing seal failure was the source of the oil vapor. An engine change was necessary. The flight crew had to use their O2 masks and the reporter found it difficult to put the mask on over eyeglasses and ear piece. Also, the microphone in the O2 mask garbled flight crew radio transmission. The company is changing over from cockpit speakers to radio headsets and plans to include practice in donning and using the O2 masks in recurrent trainers.
