Try businessballs.com
It's a great site for all sorts of management stuff and includes some very good ideas for how to present sales plans, strategic road-mapping etc. all of which would be useful for your presentation.
I had to do a similar presentation once, I included an overview of how I would integrate into the business; what objectives I would set myself to achieve in that timescale; getting to know my team/people and how I would do that... past achievements and how you might apply similar principles in this role would also be good to include.
Keep it simple, keep it short, bullet points only and make sure its interesting enough for them to ask questions at the end.
Good luck!
