If it only slipped one tooth it might be ok but you'll need to lockup the engine at 90 degrees AFTDC on cylinder #1. Lock the flywheel at that postion and then remove the cam lock ports and check the position of the intake and exhaust cam lock hole (an inspection camera is great for this), that will tell you how far out it is. If the holes don't line up or can't be pulled into time by using the locking bolts then you will have to redo the timing belt change.
If the timing is way out then you have probably bent some rockers and maybe valves but only an intake body cover removal will be able to tell the extent of the damage.
I have to ask, how could this have occurred if the belt had been properly tensioned in the first place. You may have recourse to try and recover the cost from the people that did the timing belt change. But first you need to find the extent of the problem.
Importantly, can you turn the engine over by hand? Put a socket on the crank shaft pulley and see if you can turn the engine (clockwise) by hand, if you can the timing belt maybe ok and you need to look elsewhere.
BTW a turbo failure could result in the fumes coming out of the air box, you might want to check that as well.
