Squats (any variation so long as hips go below knees at the bottom), pushes (bench press, overhead press, push ups, dips), hinges (deadlifts, Romanian deadlifts, Olympic lifts), and pulls (rows, pull ups, chin ups, lat pull downs). Do one exercise from each of the above 4 categories every time you train, focus on technique first and foremost, then focus on getting stronger at each exercise. Do a general warm up (walking, running, cycling, rowing, skipping, etc) for 5min before training, then do lighter warm up sets of each exercise before getting into the work sets. Train 3 non-consecutive days per week. You may also do some light cardio afterwards or on non-training days if you so desire, but it isn't required - strength training is if you want to be "toned" and not just skinny/skinny-fat, thus do the 3 days per week of squats, pushes, hinges and pulls.
Consume 140g protein/day, 70g fat/day, and get the rest of your calories from carbohydrates and/or more protein/fat. Consume about 2,000kcal/day starting out (protein and carbs are each ~4kcal/gram, fat is ~9kcal/gram, alcohol is ~7kcal/gram). So, 140g protein is 560kcal, 70g fat is 630kcal. That's 1,190kcal so far, the other 810kcal can come from whatever you want.
Rather than using the scale to measure weight, go by the tape measure around the waist, how your clothes fit/feel, how YOU feel, and what you see in the mirror (or much better yet, take progress pictures every 2-4 weeks).
