Since this is your first bike, starting small and approachable would be the smart way to go about it. In that same vein, we would recommend the new Yamaha XSR155 because it is a light, comfortable, fuel-efficient machine that's also reasonably exciting to use.
If you want a larger machine, then bikes like the Honda CB300F, Bajaj Pulsar N250 and Suzuki Gixxer 250 would be good options.
Take a test ride of everything you shortlist before you decide.
