You might want to start by reading some important differences between a CV and a Resume:http://jobsearch.about.com/cs/curriculu ... resume.htmhttp://www.cvtips.com/resumes-and-cvs/c ... thing.html
If that's not enough, just Google "CV vs resume" and you'll find much more information.
The main difference is that a CV is longer and more rigorous. On a resume, you only put the best 1-2 pages that you can. On a CV, you can take much more space as long as the content is important. I've seen some distinguished professors' CVs that are over 10 pages long. Of course most of that is publication citations. But even if you don't have any publications, put every item you feel is important on your CV. Of course, you should still be concise and precise.
I think that one of the best ways to look at academic CVs is to go through CVs of faculty members on university websites. Many professors may either have their CV directly posted on the school's website, or have a link to their personal website where they would have a CV. Just open the website of the university you want to apply to, search for faculty listing, and it's more likely that not you'll find to CVs to refer to. If not, just try other universities until you find some.
Final note is to always tailor your CV to the program you are applying to -- see what requirements and desired items are on the list, and structure your CV in a way that would best highlight your knowledge and experience in those areas. For an MBA, leadership ability is very important; for a MSc/PhD, research potential is.
