First of all, consider not settling in place, if you see a hill nearby (1-2 tiles away), if you go and settle there on turn 2, you actually gain a turn towards your first build. For example: A city built on a grassland tile, will need 7 turns for a scout. Now, a city built on a hill, will need 5 turns for the same scout. That means that even if you settle there on turn 2, you will have your scout out on turn 6. Of course, it will also help with your next build, and so on.
Another thing to keep in mind, is to see if you have any deer or stone nearby. Those can provide an extra production when you research the perquisite techs for a camp or quarry respectively. As other people have suggested, you could always research animal husbandry to see if you have any horses nearby, which provide +1 Hammer when you build a pasture, and another +1 hammer, when you get to Horseback Riding, and build a stable in your city.
