According to baptist belief what do you do to be saved? I have heard many times by baptist that I need to be saved. I feel I have already been saved, but I am curious what it means to a baptist. How can I be saved the baptist way? What are the requirements?

I have heard slightly differing views on the subject. One is that if somebody murders they can lose their salvation after being saved. Another is that once you have said a prayer and accepted Jesus as your savior, nothing can separate you from salvation, even if you for whatever reason want to. Is the only requirement to say a certain prayer? Or are there requirements after? Are you still saved even if nothing changes in your life besides you said a prayer accepting Christ? I have also heard that if you say the prayer and accept Christ as your savior, but you don't change your life to show faith, you were never saved in the first place. So is a prayer and some works required to show faith? What exactly is required in order to be saved?
That's sort of like asking, "What color is a horse?"  There are horses of many colors, and many answers to the question. Still there is pretty general agreement among all 'anabaptists' (That's the name that baptists get their name from.  It just means that they believe that water baptism does not save one, and must be done after one is 'saved.')

The common Baptist doctrine is that you do nothing in the way of good works or religious works, or works of any sort to be saved.  The one essential requirement is that one puts his trust in what Jesus has done. That's called "faith" or "believing" in the New Testament ('pistiuo' in New Testament Greek). "By grace are ye saved through faith...." Having by faith in Christ placed yourself before God, He imparts His Spirit to you, and your life begins to be different, so that you can (and will) begin to honestly 'confess Christ' because you are saved.
