In terms of clothing and accessories, I recommend packing the following: a sun hat that shades your face, sunglasses with good UV protection, a light cotton scarf to protect your neck from the sun, short and long-sleeved light cotton or quick-dry shirts in neutral bush colors (no brights), a fleece or jacket for the evenings, a lightweight rain jacket, shorts or zip-off trousers and your choice of casual smart clothing for the evenings when staying in lodges / tented camps. In terms of footwear, sensible walking shoes or trainers are fine and sport sandals are also useful. A head torch (flashlight) would be very handy as well.
