Look out lighting in Maya's help (F1).

When in doubt, delete history and freeze transformations.

The answer to that question would pretty much require a tutorial as it involves real world observation and understanding lights in Maya, so its not as simple as put this here, turn this on, rotate this, boost this and thats it.

imagine the inside of this sphere is your environment. the top is obviously the sky. the bottom your terrain maybe.., unless you have a ground plane you made, which no doubt you have.

now imagine this array of directional lights.., each one looking down at different angles.., the colour for each one taken from looking back up the axis toward the 'sky'.., so some might have different colours of blue of the sky or the white of the clouds.

shadows off.

now duplicate the group of lights and rotate it 180 in X so now they look up.., these are your bounce lights and the intensities much lower than the sun group., the colour for each bounce done the same way as the sky/sun group of lights. so some might be the colour of grass, rock, dirt, road.., whatever the axis lines up with.

shadows off,

now you have your sun and your reflected bounce lights.

now create a spot, look through it and line it up how you want it, time of day considered..,

shadows on.., this spot will cast your shadows

you might have to do some lightlinking , tweak the intensities and such

doesnt need to be a sphere, this will work for any scene
