Check your bylaws -- they should spell out the procedure for removing an officer. If they don't, you should consider adding that to the bylaws. Typically, a two-thirds vote at a general membership meeting is required -- that's the procedure dictated by Robert's Rules. You would also need to announce the vote in advance --include it on a published agenda and perhaps state it at the previous meeting -- so that anyone who is concerned can be sure to attend and vote.
