In order to get a Munchlax Egg, you can use either Ditto and Snorlax of either gender or a female Snorlax and a male Pokémon that it is compatible with. Snorlax must be holding the Full Incense before you place it into the Daycare. Once you've done that, you just need to walk or bike around until the Daycare Man finds a Pokémon Egg.
You can slather some honey on a tree and it might come. (Munchlax is very rare though)
