The Oasis singer saw the group plunge into turmoil in August when his brother, guitarist Noel Gallagher, quit the band due to unbearable tensions with the singer but has promised fans he is already planning his next musical move.
He said: "I'll be back doing that, playing live, within a couple of months. I've just done a tour, I always miss singing songs. I miss the people."
Liam, 37, also confirmed he is currently working on new material with Oasis bandmates Gem Archer, Andy Bell and Chris Sharrock.
He said: "We're sort of doing things at the moment. Not Oasis, Oasis is done. But with everyone except for Noel."
Liam also claimed he doesn't believe his fight with Noel - which allegedly saw them damage each other's guitars backstage before a planned performance in Paris, France - was the reason for the guitarist's departure, insisting the musician had it planned.
He explained to Italy's Radio Deejay: "To be quite honest, I think Noel wanted out. But you'll have to ask him when he comes in and does his little solo thing. We had an argument - but we've had bigger ones, about more important people. Basically, I think he wanted out, wanted something different, but he hadn't got the b******s to tell the band or the fans."
Despite admitting to the row, Liam - who is married to former All Saints singer Nicole Appleton - insists he never hurt Noel during their altercation.
He added: "I didn't smash the guitar on him, I wish I had, man. He treated my guitar poorly, which was a present off my wife. So I thought it was only fair to pay the compliment back. So I smashed one of his. It sounds ridiculous, like a pair of old women."
