The amount of carbohydrates in vegetables is not increased when cooked. Cooking on the other hand can either make food lose water or absorb water. If a vegetable contains more carbohydrates when cooked the it's simply because it has lost water weight and therefor contains more macronutrients per 100g than the same weight of it did before it was cooked.
Vegetables with high moisture content are called "succulent vegetables." These vegetables have a high water content, which gives them a juicy and tender texture when cooked. Examples include cucumbers, tomatoes, and zucchini.

The Lakota tribe prepared food in a couple of different ways. They would sometimes dry their food, this enabled them to save food for later. They also roasted meats over an open fire. Vegetables were cooked over an open fire as well. They made pots and would add hot rocks to water in order to steam vegetables.
Leafy vegetables are primarily composed of water. During cooking, water is released from the vegetables either in the form of steam or liquid in the cooking pan (that's what makes the "sizzle" sound when you cook). When water is removed from the plants, there is simply not much left, so they appear to "shrink". To help the release of water, you can add salt, which helps to draw out the moisture.
Nutrients are not "killed". Some foods lose nutrient value when they are boiled because the vitamins go into the water, that's why it's recommend to steam your vegetables instead.
