OPT and H1 tax?

I held OPT then H1 visa last year. When I was with OPT, there is no deduction for social security and medcare. Since I have been in US for almost 5 years. I think I should be treated as resident alien for tax purpose. I was wondering what kind of form should I use? And how can I deal with two-status-in-one-year situation
