I believe (top of my head before off on duty) Continue SID or last assigned heading/altitude(FL) for 7 mins, squawk 7600 then climb to flight plan cruise level, flight plan route to destination, IAF, descend, fly approach within EAT, land.
Although different countries will have different procedures enroute and on arrival, however we would have to read the jeppy on the way.
As for returning to airfield of departure? No unless you had to.
