Read the Old Testament and New Testament together. Your knowledge of the Old Testament will be enhanced by what you read simultaneously in the New Testament.
Read the events of the Bible as they occurred chronologically. For example, the Book of Job is integrated with Genesis because Job lived before Abraham.
If you like variety, this plan is for you. For example, while you are reading the Old Testament Book of Isaiah, you will also read from the New Testament Book of Mark to heighten the variety of your Bible reading.
