The main thing that you need to get out is the fact your declaring a mayday and what your problem is - The rest can wait until your able to communicate with ATC - Aviate, navigate, communicate.
Example of a mayday call "Mayday mayday mayday, Ryanair 5437, left engine faliure we are continuing with north westerly and then inbound on the radial 083 towards Wallasey."
ATC will proberbly respond roger mayday squawk 7700, all runways avaliable for landing surface winds XXXXX - When able state intentions.
