Our church leaders (and others) have provided us with so much counsel on how we can better our teaching. Elder Bednar, in a recent video, sums it all up. I highly recommend watching the whole video.

Another one of my favorites is from the Sunday School General Presidency in 2012. Though they are not talking about the Come, Follow Me program they still have great pointers and insights that may help you. Here is an excerpt from the full video:
