What is the best way to get my 22 month old off his pacifier?

For us the easiest way was cold turkey. We started talking about it a few weeks before their second birthdays. On the morning of their birthday, we put all the pacifiers in a box and "mailed" them to a baby, because they were a big boy/girl now! It was hard for the first day or two but then they were over it. The plus side of doing it on their birthday was that they were having so much fun the whole day they barely thought about it.
