Replace spark plugs, air & fuel filter, scan for faults, check for fluid leaks, check ignition system, exhaust system & cooling system, this is what i offer my customers but this can vary from business to business, at a minimum plugs & filters and scan would be done also check ignition timing if system is manually adjusted. Some cars will require additional items like valve clearance checks, but not all need this.
