In such situations i would usually be in Aperture priority mode instead of Manual

I set my ISO setting to Auto to let the camera compensate for any wrong settings for aperture or shutter speed (refer to this question for the advantages and disadvantages of auto ISO).

Also i would set the metering mode to spot metering to get what i want in the right exposure no matter what is in the rest of the frame, this really depends on the size of your subject and how important the rest of the frame is.

Continuous focus with burst, and a smaller aperture to get more stuff in focus. Careful with this point because if you are in Aperture Priority the camera would set the shutter speed and it might be too slow, although the auto ISO really helps here.

Setting the white balance to a preset or manually would also help to get more consistent shots, keep in mind that if you set the white balance while outdoors the sun will change and clouds could move and setting the white balance would mess things up unless in auto.

for the over-exposure that is happening use the exposure compensation that always works for me, i wont go less than -1 personally

its helpful for editing the photos later to set the "picture style" to "Neutral" (I'm not familiar with cameras other than Canon so I'm sorry if those names make no sense if u don't have a Canon)
