Is it Orographic, or Convergence/frontal lifting?

Convection is certainly one mechanism. Another is due to convergence within the monsoonal trough.

Well being over the ocean, I sure wouldn't think it would be orthographic since I have not seen too many hills on top of the water. There are a few islands but they are rather insignificant and fairly flat.
Most are moisture and thermally driven. The intertropical convergence zone (ITCZ)does run through the Indian ocean which of course does provide an area of convergence for uplift as well. In fact the ITCZ is likely the biggest single source of lift triggering mechanism for the Indian Ocean. Most Indian Cyclones form within or near the ITCZ.
Not many fronts make it that far south or north into the Indian Ocean.

Convergence resulting in convection particularly near the equator(on both sides).
