1. The vain repetitions were vain because the scripture, in context, referred to the prayers of pagans not directed to the True God.
2. It's not about having things to pray about, one can focus on any concept of God while simultaneously repeating a verbal prayer on the lips. Which is an ancient method of prayer that has attended the Church for over 2,000 years.
Speaking the "Our Father" with no reverence or to just get through with it would also qualify as a "vain repetition".
