Do not just take up the pee pad. I would take a used pee pad and set it outside where you want him to do his business. When you go outside be sure to use a cue word and then have a major party with lots of treats right where he voids.
I would suggest you teach him to ring a bell hanging from the main door he is to use, so that he can alert you to when he has to go out. I googled these words: "ringing bell to go out - canine" and got a lot of hits.
You will need to have him on a long line attached to you or in a crate any time you can not watch him. Every time he has an accident in the house - it sets you back in housetraining by 1 week.
That means he is in a crate at night or he is on line and attached to you while in bed with you. That way if he gets off in the middle of the night - you are alerted and know you need to get up and get him outside. That does not mean you then take the line off. Until he is 100% reliable in the house, he remains on a line or in a crate or behind a barrier.
I do not think the problem is using the pee pad. My litter was box trained and I leave Ph'nx in an expen with a smally "potty box" lined with paper for her to use when I am at work. She uses it when kenneled but she is also well on her way to being houstrained and she is only 4 1/2 months old. Of course I also have a doggie door which makes it easier to train as she does not have to get my attention to go out - she just goes when she needs to - which she does. The point being she is able to use the potty box when she is kenneled but know she needs to go outside to do her business when she has free reign of the house.
She can hold her urine from 10pm until I get up - which can vary from 5:30 to 7:30. But then again she is crated so she has learned to hold it - which in turn expands her bladder and her ability to hold her urine.
Barring any infection - there is no reason a 10 month old can not hold his urine overnight. Sounds to me like he has no concept of the proper place to void; if he has been allowed to pee in the house - even on a pad whenever the urge hits him - he has not learned any bladder control nor perhaps has he had to hold his urine long enough to help exand the capacity of his bladder.
