-Focus on science and gold.
-Get early trade routes to nearby civs for extra beakers
-Get NC later than you would in a similar G&K: you could go markets before libraries (to try and make AIs send you more trade routes), but not much later.
-Position troops between your border and nearby AIs, if they suddenly move out with 10+ units and/or a great general, you know a war is coming and can act accordingly.
-Pay off nearby AIs to war each other. Makes it much easier for yourself.
-Get universities asap and fill all their slots for GSs and use them for Academies around your primary science city (most likely capital).
-Buy university in main science cities if you got the gold, cities without jungle aren't as important.
-Aim for extra trade route techs after science techs and buy the caravans/cargo ships if you got the gold.
-Don't bother with any of the great work wonders, tbh, although you should still build the guids. Why? Renaissance: Fill the guild slots and buy culture city states to rush through Rationalism (and make sure you have slots you can use the artists/writers/musicians to fill).
Now comes the important part: Ideologies. At this point, the AIs should start having some influence over you, meaning if you choose a different ideology than them, you will get hit on the happiness. You now have 3 choices:
1) Choose whatever you want and try to manage happiness anyway.
2) Choose whatever you want and crush whoever is influencing you the most (should be easy in most cases, since even at deity, you will now be tech equivalent or leading at this point, due to the science/gold focus) - unless they are too far away or just too strong.
3) Choose THEIR ideology so you keep your happiness up.
Each ideology have their moments, of course, but they are all perfectly fine to whatever victory you are pursuing actually.
-Beeline Research labs (bulb Plastics with Oxford) if you can manage without artillery, if not, take artillery first.
-Try to get gold and buy Research labs in all cities (it's quite cheap in gold per hammers, actually).
-Try to get the landmarks (2 culture from great tile improvements) through the world congress (should be easy, the AIs really love it themselves).
-Get hotel, airport and National Visitor Center in capital for huge tourism boost (if your happiness is dropping from ideologies). While not going for a culture victory, it still helps alot to reduce the influence of other civ's idelogies if you can get 10 or 30% influential over them (the pressure is calculated as the difference between their pressure on you and your pressure on them, so reaching those key points can help a lot).
