Change them all, then you will know what has been done.
Engine oil & filter, transmission fluid, transfer case if it's 4WD, and front & rear axles, air filter, fuel filter, spark plugs, accessory drive belts - if it has a timing belt, check the mileage, if it's over the change interval, pull the timing cover and inspect - does it look new, if not, consider replacing it.
Inspect the brakes, disks, drums, pad/linings, replace if necessary, inspect the steering linkage for looseness or play, don't forget the suspension ball joints, replace if necessary.
This may look like a formidable (and expensive list), but if you tackle it a few items at a time, it's quite manageable, and you'll be done in a month or two.
