I've found the Discipleship Journal Bible Reading Plan from NavPress to be a very helpful tool. The daily reading is divided into four parts: a portion from the gospels (usually one incident or teaching session from the life of Jesus), a portion (usually a paragraph) from a New Testament letter, a Psalm, and two chapters from an Old Testament book.
Passages for Bible study often come from my Bible reading. I note puzzling or interesting passages, then return to them for further examination.
