Exude energy.
Speak quickly. Move with vigo(u)r and purpose and use large arm movements. Frequently look at different parts of your audience.

Also remember that leashed energy can be even more effective than overt displays, so, range between controlled action and peppiness.

Be extremely inclusive
Use "we","us" & "our"; or "you" and "yours". Avoid "I", "me" & "my".

Alternate moods
Like the wave of an alterating electrical current, the mood of the presentation should sweep up and down in a continuous flow. Alternate humo(u)r, poignancy, statements about positive developments, nostalgia, hardheaded pragmatism and hope for the future.

Stress the benefits to the listeners
It may be your vision or objective; but, if they are to follow your lead, listeners need to be regularly reminded of the benefits to themselves or to those they care about.

Let them dream a little
Paint a picture of a safer community, leadership in their industry, research breakthroughs or funding records. . . . then, show them the pathway to get there.

Suggest targets
Establish attainable short term goals as the first steps on the path to the broader vision

Paint a lot of word pictures
Use them to make the targeted possibilities more familiar, and, therefore, more attainable.

Be interactive. Call out questions. Refer to individuals. Ask for a show of hands. But always keep up the pace.

Use stories
Stories of others who have successfully done what you are asking your listeners to do make it easier for them to feel they can do it, too.
