Depends what you mean by "format". I mean, it hasn't really changed much since the 60s. The Doctor and one or more companions show up on a planet, there's something going, they solve it. That's roughly what happens. And fairly often, that planet's Earth. And just because you keep saying it, doesn't mean I hate everything from the new show. Unquiet Dead, Dalek, Empty Child/Doctor Dances, and Blink are all great (probably a lot more, but I can't remember much post-Fireplace). And Blink aside, the basic idea of the Doctor showing up and something going on is much the same as in the old show.
However, if by "format" you mean the standard flashy nonsense with lots of CGI but a nonsense plot and a convoluted Doctor/Rose semi-romance (Bad Wolf/Parting of the Ways, New Earth, Aliens of London/World War Three), then that's not the kind of thing I'd try and write.
