Easiest way is if your given a missed approach, before you press TOGA check the altitude selected. The is very rarely a rush to do a go around. If your above the missed approach altitude (on 777 anyway) so long as your above 1500ft if you deselect approach it will default to V/S and decent to and capture the missed approach altitude. When its level then select TOGA and follow the normal procedure.
737 does not allow you to deselect APP, hence deselecting ILS is better option, forcing APP to be dropped.
BTW: only selected autopilot needs deselecting, eg NAV 2 with CMD B
