Oddly shaped tomatoes as you described are usually caused by pollination problems. For example, night time temperatures below the optimum range of 59 to 68 degrees can contribute to both reduced pollen production and viability; some of the "Beefsteak" varieties are more prone to this problem than others. (Higher night time temperatures, especially combined with low humidity and low soil moisture can interfere with fruit set, too.) Smaller tomatoes could be caused by a difference in soil fertility, or by a reduced level of soil moisture. The fruits are made up of so much water that adequate and steadily even soil moisture is really important to produce the best tomatoes. You may want to check your soil by digging down about six inches to be sure -- a weekly deep soaking is better than a frequent light sprinkling, and a mulch will help, too.
