Limit the main points in a lecture to five or fewer.
Create effective visuals, analogies, demonstrations, and examples to reinforce the main points.
Share your outline with audience.
Emphasize your objectives and key points in the beginning, as you get to them, and as a summary at the end.
Basic Presentation Skills
Avoid reading your lectures verbatim; if you must refer to your notes frequently, combine this with lots of eye contact.
When making eye contact, actually look at specific individuals while you make a point; don’t just continually scan the room. Individuals seem most comfortable with about five seconds of sustained eye contact.
When you lecture, speak clearly and not too rapidly. If audience are busy taking notes, go even slower.
Face the audience as much as possible, rather than facing the blackboard, projection screen, or laptop.
Engage Your Audience
Focus attention early on using a quote, a dramatic visual, an anecdote, or other material relevant to the topic.
Integrate visuals, multimedia, discussion, active learning strategies, small-group techniques, and peer instruction.
Show enthusiasm for the topic and information. .
Give audience time to think and genuine opportunities to respond.
Use verbal, visual, and kinesthetic approaches such as hands-on exercises and simulations.
Handling Questions
Let your audience know if they can interrupt with questions or should save them for the end of the lecture. In either case, avoid going overtime, so there is a reasonable chance for audience to formulate and ask questions. Consider reserving 2 to 3 minutes for questions at transition points in your lecture.
On a theoretical level, using Vygotsky's zone of proximal development, I would say that the ideal lecture presents all the material that students are able to learn and none of the material that they are not yet able to learn.
On a practical level, I would say that the ideal lecture adds emotional content to the huge amount of material found in the textbooks so that students understand what parts of the material are the most foundational and most important to master at this point in their life.

I can only add that the lecturer needs to have some idea of the background of the audience so that he/she can tailor the lecture to their needs. Many times the latter is overlooked and lecture is either above or below the audience's "head", making it difficult to grasp.
