Heat oil in a wide non-stick pan and saute cumin seeds till they begin to sizzle. Add in onions and fry for 2-3 minutes on medium-high heat till lightly browned.
Add in okra and stir-fry on high heat, tossing occasionally, for a few minutes till it starts to brown along the edges and the sliminess starts to disappear.
Add in spices, season with salt and stir-fry for a few minutes mixing everything well. Lower the heat and slowly stir in the yogurt. Cook covered on low heat for another 1-2 minutes.
