You do not need any :exe here in the current state. But you need :exe in the first statement: do not ever use % in shell commands as it is not doing any escaping. E.g. if name of currently edited file contains space first line of function MD will not do its job.

You should use

    execute '!pandoc" shellescape(@%, 1) '-o ' shellescape(expand('%:t:r')) '.html'

instead. This does not apply to vim commands: :tabe %:t:r.html is fine.
