Pick a passage of Scripture to read and use the suggestions for study given by Richard Foster: repetition (read the passage several times, perhaps twice a day for a week); concentration (as you reread the passage, begin to concentrate more on the words you are reading); comprehension (as you read and reread, intentionally concentrating on the words you are reading, watch for moments when you gain new insight into the passage); reflection (ask what the significance is of what you've learned for your own life). You may want to use a few different Bible translations to read from.
Pick a book of the Bible to read (perhaps one of the Gospels of Epistles). Read slowly, only a chapter a week (reading it more than once), and to go along with your reading of a book of the Bible, read a commentary on this Bible book and/or listen to a sermon series on it.
As your read the Bible, here are a few other things you can do to enhance your study of what you are reading: write down observations or questions that you have as you read; look up any cross-references your Bible may suggest; do a word study on key words, seeing how they are used elsewhere in Scripture; create your own outline of the passage you are reading.
Beyond the Bible, you can also take time to study other books (there are some great classics of Christian literature which would be worth reading and rereading, including: The Practice of the Presence of God by Brother Lawrence, The Imitation of Christ by Thomas A Kempis, Mere Christianity by C. S. Lewis and many more). If you would like a fuller list, check out 25 Books Every Christian Should Read (Renovaré)
Another recommendation I would give to go along with the discipline of study is regular Bible readings. There are a number of apps and plans out there to choose from, but here are just a couple of recommendations:
Bible Gateway has a number of plans on their website to choose from, including: Old & New Testament (a passage form each Testament each day), Chronological (working through the accounts in the Bible in the order they occurred), Bible in 90 Days (an intensive reading program), New Testament in a Year and many more.
Read Scripture is a great app which will guide you in reading through the Bible as well, either daily or at your own pace. This app also includes short videos which provide an overview of sections of the Bible.
