Well, if you like to teach in a discussion style, how about leading with something along the lines of “today’s topic is ___________. What do you know about it? How do you feel about it? What questions do you have about it?” You can then have some great discussions…
If not, then you can always fall back on the stuctured lesson in the manual.

I agree with asking questions, but I hate those questions where the answers are completely self-evident. Everybody likes to tell personal stories, so I’d let them share experiences in a way that illustrates what you’re teaching. It usually gets discussion going. And I think, in a class where some of the attendees might be uncomfortable at best and scared to death at worst, it’s okay to divert from the lesson.

Sometimes the answers aren’t self-evident in a gospel sense (e.g., people may genuinely not know what is the purpose of temples), but questions can still be self-evident in the sense that it’s obvious what the teacher wants you to say (“So, do you think it would be better to dress modestly, or would you prefer to dress in a slutty way that will dishonor God, draw negative attention to your body, and may even be responsible for your losing your virtue?” — yeah, I know there are about 30 things wrong with that question, but that’s the point. A lot of the old “Mr. Brown” missionary discussions were that bad.) Questions that don’t call for factual information that newcomers may not have, but which let them express their interests and concerns and ask their own questions, are good. They’ll cue you into which bits of the subject you do have to teach, or to guide them into learning by the way you steer the discussion and call up scriptures.

And while your at it, how would you feel about posting your lesson notes?

You can’t please everyone being general doesn’t help anyone. Build around what you think is correct and allow discussion but keep it restrained so it doesn’t break down the whole process.
