Try to keep multiple pee pads making a track towards the place where you want him to pee.
Usually puppy will pee when they wake up or after having food (you can lift him and place him on the pee pad).. then slowly you can start reducing the pee pads For having him to pee on the pee pad,
Take his pee on a tissue and put it on the pee pad .. he will get the smell and then pee on the pee pad only Dogs will catch a habit only when they repeat it multiple times
