Take a look at the rosbag Python API example.

That writes two msg types to two different topics (chatter and numbers).

Just make sure to use the correct message types (from sensor_msgs: sensor_msgs/Imu and sensor_msgs/Image), and that, depending on whether the nodes that will be receiving these messages need it, to embed a CameraInfo topic with the intrinsics of the camera that was used as well.
