For a Grand Strategy, I'd like to consider Domination Victory via Great Scientist bulbing of Metal Casting, Machinery and Engineering. The requirements for doing this easily are avoid (prior to the bulbs) Fishing (GS will bulb many naval technologies -> Astronomy), Code of Laws (GS will bulb Philosophy), and Civil Service/Theology (GS will bulb Paper -> Education). Also, the following technologies must be researched or otherwise acquired: Aesthetics (good technology to research and trade), Mathematics (another good technology to research and trade), and Alphabet (should be easy to get in trade or steal if necessary). Researching or Oracling Construction will be required as a prerequisite of Engineering.
Ivory and Horseback Riding would also permit War Elephants, but Pikemen could fill the role of defense against mounted units if necessary.
The majority of the mainline units would be Crossbowmen, War Elephants (or some Pikeman) and Trebuchets.
Useful Great Wonders include The Great Wall (early Great Spy), The Pyramids (Representation - adds +3 Bpt to both settled Great People and specialists that cost 2 Fpt, so its useful even with somewhat low food) and Shwedagon Paya (Pacifism or Theocracy - given that we must stay Hindu, it would be good to have the early choice of any Religious Civic excluding Free Religion, especially since Gandhi is Spiritual and thus there isn't any anarchy ever). Note that we would still need Theology to build The Apostolic Palace, unless we can gain the majority vote for the Papal Election via conquest and TAP religion spread.
