Where is the sermon in a Mormon church service?

So, I'm on vacation in Utah (and still compulsively thinking C.SE!), and so I attended an LDS service. In the morning, I heard a reading from one of the Presidents of the church during the "Quorum of the Elders," then went to Sunday School, and finally witnessed the Sacrement of the bread and water. (I guess it makes sense there was no wine, but it did make me go "Huh!") After that, there were testimonies from missionaries and some music - but nothing that struck me as a sermon. Was I missing something, or was this an atypical service? I guess I was trying to understand what the "pastor"s role in the service was supposed to be - or again, is it just that Mormons are even more Baptist than baptists? If someone could explain how instruction and exhortation are primarily conferred in the LDS church Id appreciate it.
